iwlwifi: set HT flags after channel in rxon

iwlwifi: set HT flags after channel in rxon

commit 5e2f75b8993a0d83d469388b50716dd5551f2eb4 upstream.

The HT extension channel settings require priv->staging_rxon.channel to be
accurate. However, iwl_set_rxon_ht was being called before iwl_set_rxon_channel
and thus HT40 could be broken unless another call to iwl_mac_config came in.

This problem was recently introduced by "iwlwifi: Fix to set correct ht
configuration"

The particular setting in which I noticed this was monitor mode:

	iwconfig wlan0 mode monitor
	ifconfig wlan0 up
	./iw wlan0 set channel 64 HT40-
	#./iw wlan0 set channel 64 HT40-
	tcpdump -i wlan0 -y IEEE802_11_RADIO

would only catch HT40 packets if I issued the IW command twice.

From visual inspection, iwl_set_rxon_channel does not depend on
iwl_set_rxon_ht, so simply swapping them should be safe and fixes this problem.
